But I would push this into iio_trigger_alloc() and add a 'parent' parameter to the function, similar to iio_device_alloc(). This is for the behavior consistency between iio_trigger_alloc() & devm_iio_trigger_alloc(). There aren't many uses of iio_trigger_alloc(), so there wouldn't be many files to update. Since the change to "drivers/iio/industrialio-trigger.c" doesn't change behavior, I would put that as a first patch, then the updates to all the drivers in another patch. I'd also recommend a semantic patch here: @@ expression trigger, P, name; @@ trigger = devm_iio_trigger_alloc(P, ...); ... - trigger->dev.parent = P; This seems to work to generate roughly the same changes. Though, I will admit setting up spatch is a bit of a pain. There are some prebuilt binaries though: https://coccinelle.gitlabpages.inria.fr/website/download.html I usually put the semantic patch into a file and run: spatch --sp-file input.cocci --dir drivers/iio pipe the output [which is a patch] into a file and apply it. There may be some options to directly patch the files [with spatch], but I always forget them. > > That only the obvious assginments have been replaced. > > Signed-off-by: Gwendal Grignou <gwendal@xxxxxxxxxxxx> > --- > drivers/iio/accel/adxl372.c | 2 -- > drivers/iio/accel/bmc150-accel-core.c | 1 - > drivers/iio/accel/kxcjk-1013.c | 2 -- > drivers/iio/accel/mma8452.c | 1 - > drivers/iio/accel/mxc4005.c | 1 - > drivers/iio/accel/stk8312.c | 1 - > drivers/iio/accel/stk8ba50.c | 1 - > drivers/iio/adc/ad7606.c | 1 - > drivers/iio/adc/ad7766.c | 1 - > drivers/iio/adc/ad7768-1.c | 1 - > drivers/iio/adc/at91-sama5d2_adc.c | 1 - > drivers/iio/adc/max1027.c | 1 - > drivers/iio/adc/mxs-lradc-adc.c | 1 - > drivers/iio/chemical/ccs811.c | 1 - > drivers/iio/chemical/scd30_core.c | 1 - > drivers/iio/gyro/adxrs290.c | 1 - > drivers/iio/gyro/bmg160_core.c | 2 -- > drivers/iio/gyro/fxas21002c_core.c | 1 - > drivers/iio/gyro/mpu3050-core.c | 1 - > drivers/iio/health/afe4403.c | 1 - > drivers/iio/health/afe4404.c | 1 - > drivers/iio/humidity/hts221_buffer.c | 1 - > drivers/iio/imu/adis_trigger.c | 1 - > drivers/iio/imu/kmx61.c | 1 - > drivers/iio/industrialio-trigger.c | 1 + > drivers/iio/light/gp2ap020a00f.c | 1 - > drivers/iio/light/rpr0521.c | 1 - > drivers/iio/light/si1145.c | 1 - > drivers/iio/light/st_uvis25_core.c | 1 - > drivers/iio/light/vcnl4000.c | 1 - > drivers/iio/light/vcnl4035.c | 1 - > drivers/iio/magnetometer/bmc150_magn.c | 1 - > drivers/iio/magnetometer/rm3100-core.c | 1 - > drivers/iio/potentiostat/lmp91000.c | 1 - > drivers/iio/pressure/zpa2326.c | 1 - > drivers/iio/proximity/sx9310.c | 1 - > drivers/iio/proximity/sx932x.c | 1 - > drivers/iio/proximity/sx9500.c | 1 - > 38 files changed, 1 insertion(+), 40 deletions(-) > > diff --git a/drivers/iio/accel/adxl372.c b/drivers/iio/accel/adxl372.c > index aed2a4930fb0..f21b1f414271 100644 > --- a/drivers/iio/accel/adxl372.c > +++ b/drivers/iio/accel/adxl372.c > @@ -1237,8 +1237,6 @@ int adxl372_probe(struct device *dev, struct regmap *regmap, > > st->dready_trig->ops = &adxl372_trigger_ops;
